n Page 41 of PS 731 (Oct 13), we said that FM 4-20.198,
Multiservice Helicopter
Sling Load: Single-Point Load Rigging Procedures
and FM 4-20.199,
Multiservice
Helicopter Sling Load Dual-Point Load Rigging Procedures,
hadn’t been converted
to TMs. That’s no longer true.
The FMs are now TM 4-48.10,
Multiservice Helicopter Sling Load: Single-Point
Load Rigging Procedures,
and TM 4-48.11,
Multiservice Helicopter Sling Load
Dual-Point Load Rigging Procedures.
You can ±nd them on the APD website:
The article also stated that all loads must be rigged by an air assault-quali±ed
person. That needs a little more clari±cation.
Rigging can be done by anyone the unit authorizes to rig the load. The ±nal
inspection must be done by someone who is air assault- or path±nder-quali±ed or
who is quali±ed through the sling load inspector certi±cation course (SLICC). That
person should
not
be involved in the original rigging.
Doing sling loading operations right means doing it by the book, not by the seat of
your pants.
O
nly you can prevent damage to your Chinook
anti-collision light, mechanics.
The key is to make sure the cockpit ²ight
controls stay centered after ²ight. That way, the
blade dampener can’t hit your aircraft’s anti-
collision light when the rotor blades are angled.
If you change or move the ²ight controls while
performing maintenance, the rotor blades and
rotor head pitch varying housing are adjusted to a
pitched angled position.
When you rotate the angled rotors while they
are pitched, you can be certain the anti-collision
light will get smashed by the blade dampener
on the aft rotor. You can’t ²y without the light
because it’s an FAA requirement.
